repacking batteries Nissan Leaf

i will be here I will repack here then repack packed back to the lift we put it back on the car watch how it will be with us start up so see here what we will succeed so, well, we brought a battery in the city will be carried out and repacking now I will wash her because she is covered in dust dirty and I’ll start to slowly disassemble and and see what will be inside of us so guys but dude i took off the lid with battery here simple procedure and wanted you a little how to talk about the battery let’s quickly go over maybe someone not knows that it is considered that it is back their modules and batteries are 24 pieces and 12 means left front modules and right sensors are sitting here temperatures in each module here is one two sensor so in the rear modules so here is one and here second it is considered the right back it central rear and one temperature the sensor is on the right side too front module means here we have the relay module is completely turns on and off the whole battery service connector and that’s how it goes voltage in the battery means there is a plus minus he plus goes first to the rear back not the modules runs them all then through the service connector runs into the bottom of the module and rises on them runs from this module and goes to the right modules to the right of the module it is here from above it turns out already and from below it’s already minus and goes as if to a motor here we start now with this slowly disassemble so on i now picked up contacts, that is, here we have plus came here minus embroidered making service connector so as not to break the circuit we get 380 volts even look i am taking now zealously tear us apart voltage drops we put on the service connector again bad contact here is 380 volts well i’m here now measured that is obtained in these blocks we have somewhere 90 with something volts in volume 90 volts and it turns out moderately mean back lessons service socket hour 190 volt that’s back studios blocks thinking now how would we sort it all out I think we will not be wise with we also try to lay wiring our new modules i.e. there are also 24 put modules and 12 modules here and here so that we have all the temperature the sensors are in place then only replace items due to began to disassemble the battery and saw which well done japanese that is, I’m shooting now temperature sensors and what you then with I didn’t confuse the assembly it turns out the connection sensor control goes momada dad here such a chip and he has a sensor on the contrary, mixed up contacts and I can’t connect it in another way sensors because chips then they have a kind of bottom and change that is, in this mom goes on at the entrance to the country is getting and this is going dad at the entrance she herself the sensor mom goes such things, well, without wiring, it’s not so scary everything looks everything turns out only it didn’t hit me you can continue work on, we begin to remove modules so but little by little everything is sorted out it remains to disassemble only the rear modules here I am these modules that were in front left and right pulled out all now I want to weigh them see what it turns out not quite heavy it turns out we cho it is three kilograms 800 almost 380 grams like that and the modules that we will put 2 to 10 well here they are weigh 800 kilograms, i.e. 2 kilograms easier and the capacity we have here will be 60 amperes and in those the remainder is 40 amperes so well, let’s do it all further everything and we will think how to put new so what is the finished work on battery removal laid out here so here we will wiring there is relay module service connector and than and let’s do it now let’s take one package I’ll open for a long look packed items so for the sake of interest and we will be already on finish this for now curiosity is the most interesting quality therefore, one package could not resist revealed there is this here it is canned but the neat Bulgarian perimeter cut through than I flew opened my surprise It was something that is written in the instructions what should be there two packages inside there are actually four packages inside so they are visible 1 2 3 4 4 packages and not so connected here that is minus plus we are connected so this is the stigma of 4 volts if you compare some minutes with this go complex to this solder connect among themselves, such things are nothing guys while we will end here in a series with battery analysis now I I’ll think about how to put in new elements and how connect them and probably the next series we’ll see it all, try compote then he would sleep wiring as we will lay out most batteries but that’s it
